You calculate the margin on a shawarma sandwich by adding up all ingredient costs and subtracting them from your selling price excluding VAT. While many restaurant owners obsess over complex profit calculations, snack bar operators often skip the small ingredients like sauces and vegetables. This oversight causes them to underestimate their true profitability by 5-10%.
Gather all ingredient costs
For a complete margin calculation you add up all ingredients that go into the sandwich. Even the small things like onion, tomato and sauce count.
💡 Example ingredient list shawarma sandwich:
- Pita bread: €0.35
- Shawarma meat (120g): €1.80
- Garlic sauce (20g): €0.12
- Sambal (5g): €0.03
- Lettuce (15g): €0.08
- Tomato (20g): €0.15
- Onion (10g): €0.04
Total ingredient costs: €2.57
Calculate your selling price excluding VAT
Your menu price includes 9% VAT. For margin calculation you always work excluding VAT.
Formula: Selling price excl. VAT = Menu price / 1.09
💡 Example:
Shawarma sandwich on menu: €6.50 (incl. 9% VAT)
Selling price excl. VAT: €6.50 / 1.09 = €5.96
Calculate food cost and margin
Now you can calculate both your food cost percentage and your absolute margin.
- Food cost %: (Ingredient costs / Selling price excl. VAT) × 100
- Absolute margin: Selling price excl. VAT - Ingredient costs
- Margin %: (Absolute margin / Selling price excl. VAT) × 100
💡 Shawarma sandwich calculation:
- Ingredient costs: €2.57
- Selling price excl. VAT: €5.96
- Food cost: (€2.57 / €5.96) × 100 = 43.1%
- Absolute margin: €5.96 - €2.57 = €3.39
- Margin %: (€3.39 / €5.96) × 100 = 56.9%
Benchmark for snack bar margins
Snack bars often have a different cost structure than restaurants. Food cost is usually higher, but you have less service and overhead.
- Standard food cost snack bar: 35-45%
- Shawarma/kebab: often 40-50% (meat is expensive)
- Fries/croquette: often 25-35% (cheaper ingredients)
⚠️ Note:
A food cost of 43% is on the high side, but can still be profitable if you keep other costs low. Check your meat prices regularly - they often go up.
Where is your margin leaking away?
With shawarma there are a few common mistakes that eat into your margin. From analyzing actual purchasing data across different restaurant types, these issues show up consistently:
- Too generous meat portions: 10 grams extra = €0.15 less margin
- Meat waste: shawarma that stays warm too long becomes dry
- Free extras: "a bit extra sauce" costs €0.05 each time
- No portion control: different staff members give different amounts
💡 Impact calculation:
You sell 200 shawarma sandwiches per week. Through better portion control you save €0.20 per sandwich.
Savings per year: €0.20 × 200 × 52 = €2,080
Digital margin control
Many snack bar owners track margins in Excel or on paper. With tools like KitchenNmbrs you see your food cost and margin per product directly, and can quickly calculate what price changes mean for your profit.
How do you calculate the margin on a shawarma sandwich? (step by step)
Make a complete ingredient list
Write down all ingredients with exact quantities: pita, meat, sauces, vegetables. Don't forget anything, not even the small things like onion and spices.
Calculate the costs per ingredient
Add up all ingredient costs together. Calculate what each portion costs based on your purchase prices and the quantities you use.
Convert your selling price to excluding VAT
Divide your menu price by 1.09 to get the price excluding VAT. You need this for a correct margin calculation.
Calculate food cost and absolute margin
Food cost % = (ingredient costs / selling price excl. VAT) × 100. Absolute margin = selling price excl. VAT minus ingredient costs.
✨ Pro tip
Track your meat waste for 2 weeks by weighing what you throw away daily. Most shawarma shops waste 8-12% of their meat through overcooking or keeping it warm too long - that's €150-300 monthly profit lost.

Frequently asked questions
Should I include VAT in my margin calculation?
No, always calculate excluding VAT. Your menu price of €6.50 becomes €5.96 excl. VAT (divide by 1.09). Only this way do you get a correct margin.
What is a good food cost for shawarma sandwiches?
For shawarma the food cost is often between 40-50% due to high meat costs. That's higher than restaurants, but still profitable with low overhead.
How do I prevent my margin from leaking away through too generous portions?
Use a scale and train your staff on fixed portion sizes. 120 grams of shawarma meat per sandwich, no more. Every 10 grams extra costs you €0.15 margin.
What if my supplier raises meat prices?
Calculate immediately what this means for your margin. With a 10% meat price increase your food cost rises from 43% to 47%. Then consider adjusting your menu price.
How often should I recalculate my shawarma margins?
Recalculate monthly or whenever ingredient prices change significantly. Meat prices fluctuate weekly, while vegetables vary seasonally. Set up alerts for when your food cost exceeds 45%.
Should I weigh every single ingredient for accurate costing?
For expensive items like meat, yes - weigh every portion. For cheap items like onions or lettuce, you can estimate based on average usage per sandwich to save time.
